1.4 OPERATING TIPS
The following conditions tend to reduce effective range and
should be avoided whenever possible.
• Operating the radio in areas of low terrain, or while
under power lines or bridges.
• Obstructions such as mountains and buildings.
• In areas where transmission or reception is poor, some
improvement may be obtained by ensuring that the
antenna is vertical. Moving a few yards in another
direction or moving to a higher elevation may also
improve communication.
1.5 OCCUPATIONAL SAFETY GUIDELINES
AND SAFETY TRAINING INFORMATION
CAUTION
To ensure that exposure to RF
electromagnetic energy is within the FCC
allowable limits for occupational use,
always adhere to the guidelines below.
The DB800 can transmit using a replaceable antenna. When
the radio is ON, it receives and also transmits radio
frequency (RF) signals. In order to maintain registration, the
radio periodically transmits, even when the PTT switch has
not been pressed.
